Description
Technical field
The invention belongs in petroleum exploration and development process about borehole wall stability technical field, relate to a kind of containing crack
Shale stability evaluating apparatus and method.
Background technology
Mud shale wellbore stability always perplexs a big difficult point of petroleum exploration and development.Now with China's shale gas
The quickening of resources exploration strategy paces, research worker focuses more on mud shale basic physical mechanics properties pearl and grinds
Study carefully.Because the mud shale Wellbore Stability run into during shale gas exploration and development and the leakage of Fractured mud shale
Geological environment, formation fluid distribution situation, crustal stress and the engineering factor condition that problem is all deposited in tax with mud shale
The physical and mechanical property that lower mud shale is shown has the relation of interwoveness.The most indoor for mud shale well
The experiment that wall stability is launched is broadly divided into two big classes: one is direct experiment method, i.e. measures drilling fluid straight to the borehole wall
Connect the degree of effect, such as dispersibility, dilatancy, Hydrogeochemical anomaly, membrane efficiency etc.；Two is indirect experiment method, i.e.
The various factors of determination influences borehole well instability, as rock forming mineral proximate analysis, scanning electron microscope structural analysis, sun from
Sub-exchange capacity, specific surface area etc..These are the most rarely seen for the physico mechanical characteristic achievement in research of mud shale, but
It is that the estimation of stability for the hard brittle shale containing crack is studied the most seldom.Generally believe containing crack in engineering
Shale stability by the fracture pore pressure transmission under drilling well liquid columnpressure effect, aquation deforms is affected ten
Dividing notable, cause the mechanical strength of fracture formation weaken and miss, therefore the hard brittle shale containing crack is steady
Qualitative evaluation research is emphasis and the difficult point of this area research.Owing to traditional method for estimating stability is not suitable for
Containing the estimation of stability of crack mud shale, thus it is specifically designed for the side evaluated in the shale stability containing crack
Method, current studies in China relatively fewer.
At present, the domestic test method for Lab-evaluation borehole wall stability mainly has following several:
Dispersibility (response rate) is tested: include following two: (1) shale roll experiment, this experiment be by
According to the experimental technique worked out in SY/T5613-2000 " mud shale physicochemical property experimental technique ", rolling is used to add
Hot stove and high-temperature tank complete experiment.The method is mainly used in evaluating the dispersibility of mud shale, and stratum is divided by drilling fluid
The suppression degree of the ability of dissipating.(2) being CST (capillary suction time) experiment, this experiment can measure liquid
By the time needed for characteristic filter paper subscript set a distance, for evaluating mud shale deployment conditions in water.
Dilatancy is tested: include that the experiment of normal temperature and pressure dilatancy and High Temperature High Pressure dilatancy test two kinds.Its experiment
Principle is, first measures the volume/highly of the dry mud shale of certain mass, then surveys mud shale and contact certain time with test solution
After volume/highly, it expands volume and accounts for the percent of former state volume/height and be referred to as the expansion rate of this mud shale,
Both of which can be used for the performance of OPTIMIZATION OF DRILLING FLUID system.
The experiment rock sample that dispersion and dilatancy experiment use is the people that formation suppressed after smashing to pieces again by actual rock sample
Lithogenesis sample, this experimental implementation substantially destroys the architectural characteristic (crack, layer reason characteristic) of original rock sample,
It is not particularly suited for the estimation of stability containing crack mud shale.
The determination experiment of Hydrogeochemical anomaly: presently preferred is to use strain gauge method to be measured.Experimental principle is profit
Derive in the form of a signal around rock sample one week, the deformation occurred after rock sample is contacted with test solution with foil gauge, and real
Testing the strain of front rock sample is 0, and difference the most between the two is Hydrogeochemical anomaly value.
The determination experiment of membrane efficiency: mainly completed by following two method: (1) utilizes difference in chemical potential effect
Under pressure transmission effect；(2) the resistivity difference utilizing different ions concentration (chemical potential) measures film effect
Rate.
Additionally, the method for Lab-evaluation shale well wall stability is the most more, such as: the mensuration of dielectric constant is real
Test, shale stability index method, rock core immersion test, X-ray diffraction are tested with scanning electron microscope, mud shale compares table
Area estimation experiment etc..These experimental techniques emphasize particularly on different fields a little, the most directly or indirectly set up drilling fluid and the borehole wall
Contact between Wen Ding, but many with complete rock core as object of study, fail to reflect drilling fluid in drilling process
It it is the quantitative-qualitative analysis of borehole wall stability that how to interact with fracture formation, to accomplish.
Although the evaluation methodology below relating to wellbore stability is relatively advanced, but all pay close attention to borehole wall damage situations, not yet
It is concerned about fracture pore pressure transmission and aquation strains these impact key factors containing crack shale stability:
Chinese patent CN200420096536.X discloses a kind of high temperature, high pressure borehole wall stability experiment: this reality
Test and have employed Circulating System in Manmade, utilize acoustic measurement+signal acquiring system to measure the borehole wall by drilling fluid
The deformation extent washed away and the impact of wall building situation.

Cross ultrasonic measurement and imaging means simulation the borehole wall by expanding, the undergauge after outside fluid etch and collapse and journey
Degree, real-time monitored can survey the degree and wall building situation rinsed, for overall merit drilling fluid completion with the record simulation borehole wall
Liquid provides new integrated test facility to the impact of borehole well instability and the degree that collapses.
Chinese patent CN201410012192.8 discloses a kind of evaluation methodology simulating full-size well wall stability,
The method utilizes full-size well wall stability simulator that rock core is applied the confined pressure required by experiment, pore pressure, water
Concora crush power, overburden pressure, mud circulating pressure and circulation of drilling fluid medium, and surveyed by caliper logging instrument
Measure the expanding situation of rock core well during experiment, by stratum slide wave sound velocity test system, measure
In experimentation, rock sample acoustic wave character change at the borehole wall after the immersion of drilling fluid under different circulatory mediators, passes through well
Wall is visual and imaging system directly observes the well actual change situation after mud soak.The method is main
For full-hole core wellbore stability analyze, though can simulate truly subsurface environment, dynamic the evaluation borehole wall steady
Stable condition, can change circulatory mediator, contributes to preferred drilling mode and drilling fluid system；Can the nearly well of overall merit
Wall stratum permeability and acoustic wave of rock characteristic, it is achieved borehole wall imaging etc..But, this simulator can not be simulated containing splitting
Expansion strain, fracture formation pore pressure that the imbibition under ground environment of the seam mud shale produces penetrate rule
Important factor in order Deng borehole wall stability.
